The whole house reinforcement leveling means that when the building is decorated, the wall plastering area is large, and the mortar is used on the wall to make a small gray cake (also known as dot) at a certain distance before plastering, and then the mortar is continued to make one or several gray bars (generally not more than 1.5m spacing) in the vertical and horizontal directions of the small gray cake to control the thickness and flatness of the plaster, this process is called dot punching.
Before plastering, determine the thickness of the paint on the wall, and the block mortar made to ensure the horizontal and vertical degree is used to control the construction quality, which is generally 50mm square.
